IMPROVEMENT IN AJUs'rABnn boca-sinne.

The Schedule referred to in. these Letters Patent and making part of the same.

To all whom it may concertar@ I Be-itknqwn than, Mismas ARMS'TRNG, crei# rard,in1th e county of Macoupen and State of Illinois, havaeinvented a new `and. useful `Improvement in Adjustable Door-Sill ;4 and I do .hereby declare-1 that j the following is a full, clear, -and exact'description `weather-strips, and consists the Arelative arrange;

ment and '-ccnstlnction scribed(V I I In the accompanyingT drawing- Figure 1 represents annside 'elevation of the door thereof, as hereinafter dei `and theslu'roundingcasing, with rthe sill madeto op-` Y erateaccordingto my inventioihj" Figure 2 is a vertical crossfsect-ion of fig. 1 on the f Similar letters of referenc'indicate corresponding parts.

A is the door.,. ,v B represents the casing.- I G is the adjustable sill, which is hinged'to the base This a stable sill 4O "iayxibe Inade of eitlierivood or I netahicr of -combination .of the two.

In this example of `my invention itis niadeoflvood -with a metallic plateor strip, 11, attachedtheretoY H is a'plate` or strip of rubber or other-material, which'is attached tothe door, and may be made, by-

means of slot-holes, adjustable on the door, so that a tight joint 4witllthe plate F rnayalways be insured.` Theanpper side of this h'ook actsas an4 inclined plane whenthedoor is closed, and raises vthe sill into the position seen in iig. 2. l

The plate F projects slightly over the edge of the sill. The hook is rigidly attached to the door, and stands at an ngle of about forty-five` degrees,.wth its point below't-he bottom of the door.

When the door is closed the point' of the hook is inserted beneath the plate, and enters a cavity in the sill, as seen in the drawing. -As this is done, the edge of theplate 'F slidesnp Von the hook until it strikes'the bottom of the door or the edge of the `plate H.' i he hook may be 'so adj usted that when the door is entirelyl closed, the sill .and plate F will be tightly pressed against the door or the plate H, thns insuring a good joint and affording a sure protection against 'wind-and water. Y

IWhen the door is open the sill drops down into the Vrecess K by its own gravity while the projecting edge of the plate F allows the point of the. hook to catch I under it, as before stated, when the Vdooris closed.

-By this arrangement the door may be made shorter than thedoor-frame, so that` carpets are in no danger from the opening of the saine.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent The` hinged sill C, having inclined plane infront, recessed base D, hook I J, projecting metal plate F,

rubber H, and shortened door A, inclined on its'bot.

torn face, all combined, constructed, and relatively arranged, as and for the' purpose specified.
